In African Americans, the problem can occur as early as age 2.
The winter flounder is one of five species in the genus Pseudopleuronectes along with the Yellow-striped flounder, Cresthead flounder, Marbled flounder, and Dark flounder. It is the only cogener to inhabit the Atlantic Ocean.
The summer flounder, the winter flounder and the southern flounder are all found in the western Atlantic Ocean, while the European flounder is found in the colder waters around Northern Europe. All five flounder species are very similar in appearance but can vary quite dramatically in size.
